Slipknot is a heavy-metal band consisting of nine members, all of whom are male, who became popular because of its extreme music and dramatic stage performances. This group was first formed in the late 1995 in the unlikely locale of Des Moines, IA. It had 3 percussionists, 2 guitarists, 1 bassist, a DJ, a sampler and a lead singer. Aside from their real names, members of the band are also referred to by numbers 0 through 8 and each of them also wears a mask, which they said is part of their personality, like an extension of their body. To explain that, all the group members believe that wearing the masks shows more of what they are like inside and what the music does to them inside.
